Import an SDTM or ADaM file or directory of files

Usage

import_sdtm(
  path,
  extension_choice = c(".sas7bdat", ".xpt"),
  ignore_case = TRUE,
  auto_supp = FALSE,
  auto_dtc = FALSE,
  ...
)

import_sdtm_dir(
  path,
  extension_choice = c(".sas7bdat", ".xpt"),
  ignore_case = TRUE,
  ignore_filename = c(),
  ...
)

import_sdtm_file(path, return_type = c("data.frame", "list"), ...)

Arguments

path: The path to the directory or file.
extension_choice: What file extension(s) should be searched for within the directory? (If more than one file with the same extension exists, the first extension in extension_choice with a usable file will be used, and a warning will be given for subsequent files.
ignore_case: Passed to list.files when loading a directory.
auto_supp: Automatically combine –SUPP data with the main SDTM domain and remove the –SUPP data from the returned list of data.frames.
auto_dtc: Automatically convert –DTC columns to date/times?
...: Arguments passed to rio::import
ignore_filename: A vector of filenames not to load (case sensitive, filename only excluding directory name)
return_type: When loading a single file, what type of output should be provided?

Value

If a directory or a vector of files is given in path, a list of data.frames; the names of the list will be the uppercase basename of the file without the extension. If a single file is given in path, a data.frame.

Details

It is an error to import the same filename base (filename without path or extension) more than once. That can happen by loading more than one file with the same name from different directories or multiple versions of the same file.

Functions

import_sdtm_dir(): Load a directory of SDTM files.
import_sdtm_file(): Load a single SDTM file.
